Solar PV.

Energywise Ireland are one of Ireland’s leading installers of solar PV panels. Most solar PV systems are installed in a single day. Energywise Ireland completed its first Solar PV install in 2013, since then we have seen the demand for Solar PV increase every year. With the constant rise of electricity cost, with the available grants and 0% VAT on PV panels, now is the right time to install Solar PV Panels on your home.

We offer our customers the best products available on the market. We supply our customers with Longi Solar PV Panels who are the largest manufacturer of solar panels in the world.

The panels have salt mist resistant certification so they can be used in coastal areas where sea air can be a problem. With higher wattage panels, this gives more flexibility to customers who are limited with roof space where they are getting more power per m2 of roof space. The Longi panel is the absolute cutting edge of solar panel design ready for the 2023 year.

How Does the Process for Installing a Solar PV System Work?

How do solar PV panels work?

Sunlight is made up of photons, and when it hits the semi-conductor metal of the PV panel, electrons are released; these electrons form a direct current. People have been using PV for years, for example Sharp release their first pocket calculator in 1976 which has a number of PV cells. A typical solar PV systems consist of three main elements:

The inverter is an electronic device that converts the DC electricity produced by the solar array into AC with the same voltage and frequency as the mains supply. The inverter also performs various safety functions, constantly monitoring the grid and switching off in the event of a fault or major fluctuation in mains supply. The output of the inverter goes directly into the building’s fuse box – feeding solar electricity into the building’s conventional electricity supply which means you will not have to buy so much electricity from your electricity supplier.
The appliances in the building will use the free electricity generated from your solar PV system and any surplus power will automatically be exported into the grid so that others can buy the “green” electricity you have generated Most solar PV systems are grid connected, which means that the electricity generated is fed directly into (and synchronised with) a building’s existing mains supply.
On a sunny day, the power generated by the solar PV system reduces the amount of electricity that needs to be bought from the electricity supply company. On very sunny days, or at times when not many loads are turned on, the PV may generate more power than is needed in the building, and the surplus will be exported out into the grid. There are six main factors that will impact how much energy a Solar PV system will generate:

Does Solar PV work in Ireland?

There is an opinion out there that Solar technology would not work in Ireland , this stems from people thinking that we don’t get enough sunlight in the summer, never mind the winter. This however is not true, photovoltaic cells work on sunlight as opposed to the heat from the sun. In fact, Ireland has the same annual Irradiation levels as many parts of central europe, ranging from 1200 kWhr/m2/yr in the south of the country to 1000 kWhr/m2/yr in the north of the country, a good average for the entire country is 1100 kWhr/m2/yr. If you consider our typical winters would not be as bad as many parts of central europe, our mild climate is ideal for solar installations, as we never get too hot or too cold and we have good light levels for a large part of the year.

grant

Domestic Grant

Home owners can apply for a Solar PV grant through the SEAI, the value of the grant is capped at €2,100 and depends on the size of your install. This grant is available to all homeowners, including landlords, whose homes were built and occupied before 2021 can apply. This is defined as the date your electricity meter was installed. This is different to other grant measures where the home must be built before 2011.

What to do with excess electricity?

Depending on what size system you have and what your electrical needs are, you have several options when it comes to excess electricity.
Solar-pv-battery

Ergocell Hybrid inverter & Battery Storage

The Ergocell Hybrid Inverter and battery storage is the perfect solution to store your excess energy generated from your Solar PV panels. The Ergocell Hybrid inverter comes in up to 5kW of capacity.

Hot Water Diverter

The Eddi hot water diverter can take excess generation from you Solar PV System and divert it towards heating your water, thus heating water on 100% self-generated green energy.
Hot-water-diverter
Zappi 6

Electric Car Charger

Did you know you can charge your EV with Solar PV? Zappi allows you to divert energy from your solar PV system directly to your electric car. This is essentially free travel.

Feed in Tariff

The feed in tariff will allow you to send excess electricity generated from your Solar PV system to the grid and receive a certain amount of money per unit sent to the grid.
Feed In Tariff
energy-monitoring

Energy Monitoring

We also supply our customers with energy monitoring solutions which can report live data. I.e. Generation, Consumption and Excess energy being exported back to the grid.

Ground Mounted Systems

If space on the roof doesn’t lend itself to a sufficient or desired number of solar panels and you have adequate space available on your property, we can also provide ground mount systems. The panels can be set at the optimal tilt and orientation to achieve the maximum generation. Again, we provide the full installation from ground preparation, trench for cable, fitting etc.
